+## Using Correlation IDs to investigate distributed requests
+
+The GitLab application passes correlation IDs between the various components in a request. A
+correlation ID is a token, unique to a single request, used to correlate a single request between
+different GitLab subsystems (for example, Rails, Workhorse). Since correlation IDs are included in
+log output, Engineers can use the correlation ID to correlate logs from different subsystems and
+better understand the end-to-end path of a request through the system. When a request traverses
+process boundaries, the correlation ID is injected into the outgoing request. This enables
+the propagation of the correlation ID to each downstream subsystem.
+
+Correlation IDs are normally generated in the Rails application in response to
+certain webrequests. Some user facing systems don't generate correlation IDs in
+response to user requests (for example, Git pushes over SSH).
+
+### Developer guidelines for working with correlation IDs
+
+When integrating tracing into a new system, developers should avoid making
+certain assumptions about correlation IDs. The following guidelines apply to
+all subsystems at GitLab:
+
+- Correlation IDs are always optional.
+  - Never have non-tracing features depend on the existence of a correlation ID
+    from an upstream system.
+- Correlation IDs are always free text.
+  - Correlation IDs should never be used to pass context (for example, a username or an IP address).
+  - Correlation IDs should never be _parsed_, or manipulated in other ways (for example, split).
+
+The [LabKit library](https://gitlab.com/gitlab-org/labkit) provides a standardized interface for working with GitLab's
+correlation IDs in the Go programming language. LabKit can be used as a
+reference implementation for developers working with tracing and correlation IDs
+on non-Go GitLab subsystems.
